Hmm if I open this link on my laptop or mobile (http://192.168.1.20:3200/eui/index.html#/controls/6425764612372692992/6425764612389470208/dynamic) I am able to control the TV / receiver (only if the recipe has started).
I can now start a recipe from my Homey, so it would be great if you can redirect to this page on your phone after starting the recipe so you can control your TV after starting the recipe. Is there no “open url” option in Homey?
